This invention relates to a cook or tap for liquids, gases or vapors ofall kinds of the type provided with a cock-plug in the form of aerforated sphere. The plug is connect.- 6 ed with the operatingmeans,for instance the handle of the cock, so loosely that the sphere cansettle freely upon its. seat. In the known devices of this kind,however, the seat bore of the cock is equal to or only 'immaterially thesphericalplug. This presents the disadvantage that, withrotation 'of thesphere, the edgesi of the plug bore catch on the edges of the seat boreand w tllius cause damage to the seating and to the u P T his defect isavoided, according tothe present invention, by making the bore of theseat in the cock housing for the sphere considerably larger than thebore in the sphere.

I Catching of the edges of the] bore in the sphere'on the seat bore isconsequently, ma-

terially lessened. The substantially larger bore of the seat also givesthe sphere a more reliable seat and prevents the sphere rising out ofits seat when rotated.

Oneembodiment-of the invention is illustrated by way of example in'theaccompanying drawing in which;

Fig. 1 is a vertical section through the cock and Fig. 2 a horizontalsection thereof.

The cook housing is indicated by the reference letter a. The liquid orgas enters at b and emerges at c; The cock is connected to any pipe orvessel or the like b flanges d,

A spindle form which a ban le, handwheel or the like is secured at g isguided and packed in a stng box 0. In the interior of the housing thestem has a pivot pin is that connects the sphere z and the stem. The

I sphere constitutes the plug of the cock and is adapted to rest on theseat I of the cock housing- The spherical plug 5 is furnished with abore m for the passage of the liquid or gas from one part of thehonsing'to the other.

of the seat 1 upon prevented.

Since the valve stem 7 is connected with the sphere 2' by a pivot 12.,the sphere i is capable of automatic adjustment on the seat Z andtherefore always forms a good tight closure The spherical valve isinserted in the casing through an opening closed by a plug a.

What I claim is:

1. A cock or tap comprising a housing having a fluid inlet, a fluidoutlet and a seat hav- I ing a passage therethrou h and a right angledseating surface a spherical plug having a substantially diametricalpassage therethrough considerably smaller than the passage t rough saidseat, a stem to rotate said plug, and a pivotal connection between thestem and plug to permit the latter to freely seat.

2. A cock or tap comprising a housing having-a seat having a passagethere'through, a fluid inlet and a fluid outlet, a spherical plug havinga diametrical passage therethrough considerably smaller than the passagethrough the seat in said. housing, a stem for rotating] the plug and aloose connection between t e stem and plug to permit the plug to freelyseat. 7 A cock or tap for controlling fluids'comprlsing in combination,a housing with an 89 inlet and an outlet for the fluid, a sphericaliplug having a diametrical passage there- 'through and rotatable in saidhousing, a seat for the plug also having a passage therethrongh,the-passe e through the seat bein $5 materlally larger an the passagethrough rotation of thesph ere is testimony that I claim the foregoingas my Invention, I have si ed my name.
